General and ordering
How do I place an order?
Send your requirement through the quote form, WhatsApp, email or phone. We confirm the specification and price, then share delivery details.
Do you deliver across India?
Yes. We dispatch to customers across India. Delivery time depends on the product, quantity and location; we confirm it with your quote.
Can I get a sample?
Ask for a sample with your enquiry and we will confirm availability.
Do you make nozzles to a drawing or sample?
Yes. Send a drawing, photo or sample with your process details.
How long do plastic nozzles last?
It depends on pressure, the liquid, temperature and any solids present. Check flow and spray pattern regularly and replace a nozzle once its flow rises noticeably or the pattern becomes uneven.
How do I clean a blocked nozzle?
Remove it, soak it in a suitable cleaning solution and clear the orifice with a soft brush or plastic pin. Never use wire or a drill bit, which damages the orifice.

Choosing a nozzle
What types of plastic spray nozzles do you make?
Spiral nozzles, clip-on pipe clamp nozzles (full cone, hollow cone and flat fan), adjustable ball-joint full cone nozzles, air jet nozzles, tank mixing eductors, agricultural drone nozzles, crop spray nozzles and boom sprayer tips.
Which plastics are your nozzles made from?
Mainly polypropylene (PP). We also supply PVDF for hot or aggressive chemicals, PVC for low-cost water duties, and nylon or acetal for parts that need extra strength or wear resistance.
Why choose a plastic nozzle over a metal one?
Plastic nozzles do not rust, resist most chemicals, weigh less and cost less, especially in large quantities. Metal is better for very high pressure, high temperature or abrasive slurries.
Can you help me choose the right nozzle?
Yes. Use the nozzle finder on this page or send us your liquid, pressure, flow and the area to cover. A nozzle engineer will recommend the type, size and material.
Do you make custom nozzles?
Yes. We make all types and sizes to order. Send a sample, drawing or your process details.
Topic
PP Spiral Spray Nozzles
What is a spiral spray nozzle used for?
Spiral nozzles are used where a wide, dense spray is needed from a nozzle that will not block easily: gas scrubbers, cooling towers, gas cooling, effluent treatment and dust suppression.
Why do spiral nozzles not clog?
There are no internal vanes or small passages. The liquid exits through a large open orifice and is cut into sheets by the spiral turns, so particles pass straight through.
Can PP spiral nozzles handle acids?
Polypropylene resists most dilute and many concentrated acids, alkalis and salts. For strong oxidisers, solvents or hot liquids we recommend PVDF. Tell us the chemical and temperature and we will confirm the right material.
Full cone or hollow cone: which do I need?
Full cone covers the whole circular area and suits scrubbing and washing. Hollow cone gives a ring of finer droplets and suits gas cooling and absorption. If you are unsure, share your application and we will advise.
What information do you need for a quote?
The thread size, operating pressure, flow per nozzle (or total flow and number of nozzles), the liquid and its temperature, and the quantity you need.
Do you supply small quantities?
Yes. We supply single replacement nozzles as well as bulk orders for new plants.
Topic
Clip-On Spray Nozzles
What is a clip-on spray nozzle?
It is a nozzle with a built-in clamp that fits around a pipe. You drill a hole in the pipe, place the nozzle's saddle over it and tighten the clamp. No threaded fittings are needed.
Which pipe sizes do your clip-on nozzles fit?
Clamps are available for 3/4″ to 2″ pipe, which is an outer diameter of about 27 to 60 mm. Tell us your pipe OD and we will send the matching clamp.
What pressure do clip-on nozzles work at?
They are designed for low-pressure systems from 0.3 to 4 bar, which is typical for washing and pretreatment lines.
Can I change the spray direction?
Yes. The nozzle sits on an adjustable ball joint so each jet can be angled towards the part.
Is the clamp suitable for food or pharma lines?
The clamps are made of food-grade SS 304 or SS 316. Confirm the body material against your process liquid before use.
Where are clip-on nozzles used most?
Our biggest demand is from automobile manufacturing: paint pretreatment, coating lines and rain test booths. They are also common in parts washers and general industrial rinsing.
Topic
Flat Fan Clip-On Spray Nozzles
What is a flat fan spray nozzle?
It produces a flat, fan-shaped sheet of spray. The edges are tapered so neighbouring nozzles on a header can overlap and give uniform coverage.
How far apart should flat fan nozzles be?
Spacing depends on spray angle and the distance to the part. As a rule, set spacing so adjacent fans overlap by about a quarter to a third of their width. Send us the header height and part width and we will calculate it.
Can I use flat fan nozzles in a phosphating line?
Yes. Phosphating and degreasing are among the most common uses. Share the chemical and temperature so we can confirm the material.
Should I tilt flat fan nozzles?
Tilting each fan by 5–15° along the header stops neighbouring sprays colliding and improves coverage. The ball joint makes this easy.
Do you also supply full cone clip-on nozzles?
Yes. See our clip-on spray nozzles, which come in full cone, hollow cone and flat fan.
Topic
Adjustable Ball-Joint Full Cone Nozzles
What is a full cone spray nozzle?
A nozzle whose spray fills a solid circle (or square, depending on design) rather than a ring. It gives uniform coverage across the whole target area.
Why use a ball-joint nozzle?
The ball joint lets you set and later change the spray direction without moving the pipe, which saves time when targets are angled or change between batches.
Is this nozzle suitable for dust suppression?
Yes. Full cone sprays wet the material evenly at conveyor transfer points, hoppers and crushers. For very fine dust, a finer mist nozzle may be better; ask us.
What should I tell you to get the right size?
The operating pressure, required flow per nozzle, distance to the target, coverage width and the liquid being sprayed.
Do you have a clamp-on version?
Yes. Our clip-on spray nozzles combine a ball-joint full cone with a stainless steel pipe clamp.
Topic
Plastic Air Jet Nozzles
Why use an air nozzle instead of an open pipe?
An open pipe wastes air and creates noise. An air nozzle focuses the flow so the same blow-off force needs less compressed air, saving energy.
What applications are air jet nozzles used for?
Drying, cooling, cleaning, sorting and transporting objects on production lines.
Can I use air jet nozzles with steam?
Some designs can disperse steam. Tell us the steam temperature so we can confirm a suitable material.
Round jet or flat fan: which should I choose?
Use a round jet for spot cleaning or ejection, and a flat fan for drying or cleaning a wide surface such as a conveyor.
How do I size an air nozzle?
Share your supply pressure, line size and what you need to blow off. We will suggest the nozzle and spacing.
Topic
Plastic Tank Mixing Eductors
What is a tank mixing eductor?
A nozzle-like device placed in a tank and fed by a pump. The pumped liquid draws in surrounding liquid, so the eductor circulates much more liquid than the pump supplies.
Why use an eductor instead of air agitation?
Eductors give steady, controllable mixing without blowing air through the bath, which can cause misting, oxidation or foaming in some processes.
How many eductors does my tank need?
It depends on tank size and shape, the turnover rate you need and your pump. Send tank dimensions and pump details and we will suggest the number and position.
Can eductors be used in plating tanks?
Yes. Plating and anodising tanks are a common application. We will confirm the plastic is compatible with your chemistry and temperature.
Is this the same as a dewatering eductor?
No. Dewatering eductors are jet pumps used to lower groundwater on construction sites. Our plastic eductors are for mixing liquids inside tanks.
Topic
Agricultural Drone Spray Nozzles
Will these nozzles fit my drone?
They are designed for a 20 mm carbon fibre spray tube with a quick connection. Send a photo or the model of your drone and we will confirm the fit.
Why do drones use fan nozzles?
A fan spray gives a wide, even swath. Combined with rotor downwash, it pushes droplets into the crop canopy and reduces drift.
Do drone nozzles save chemical?
Yes. Matching the right nozzle to your pump pressure gives good coverage at lower volumes, which saves both water and pesticide.
How often should drone nozzles be replaced?
Check flow and spray pattern regularly. Replace a nozzle when its flow is more than about 10% above a new one, or when the pattern becomes uneven.
Do you supply drone service companies in bulk?
Yes. We supply single spares as well as bulk quantities for fleet operators and drone makers.
Topic
Crop Spray Nozzles
Which nozzle is best for herbicide spraying?
Flat fan nozzles at moderate pressure are usually best for herbicides because they give even coverage with coarser droplets that drift less.
Which nozzle is best for insecticides and fungicides?
Hollow cone nozzles give finer droplets that cover leaf surfaces well, which suits most contact insecticides and fungicides.
How does droplet size affect drift?
Finer droplets are lighter and drift further in wind. If you spray near sensitive crops or in breezy conditions, use a coarser nozzle or lower pressure.
When should I replace crop spray nozzles?
Replace them when flow rises noticeably compared with a new nozzle or when the pattern becomes streaky. Worn nozzles waste chemical.
Do you supply nozzles to sprayer manufacturers?
Yes. We supply bulk quantities to OEMs and dealers as well as spares to farmers.
Topic
Boom Sprayer Nozzle Tips
How do I get even coverage across a boom?
Use matched tips of the same size, keep the boom at the right height for the spray angle and nozzle spacing, and replace all tips together when they wear.
How high should the boom be?
Boom height depends on spray angle and nozzle spacing. Higher booms increase drift. Tell us your nozzle spacing and spray angle and we will suggest a height.
Can boom sprayers be used for dust suppression?
Yes. Boom sprayers are widely used to wet haul roads, yards and tracks to keep dust down.
How often should boom tips be checked?
Calibrate at the start of each season and check flow from each nozzle regularly. Replace tips that deliver more than about 10% above a new tip.
Do you sell complete boom sets?
Yes. We supply single replacement tips or a full matched set for your boom.
Topic
Polypropylene (PP) Spray Nozzles
What is a PP nozzle?
A spray nozzle moulded from polypropylene, a chemical-resistant thermoplastic. PP nozzles are used in chemical, water treatment, pretreatment and agricultural spraying.
What temperature can PP nozzles handle?
PP is generally suited to liquids up to about 80°C, depending on pressure and chemical. For hotter service we recommend PVDF. Always tell us the operating temperature.
Is PP better than PVC for nozzles?
PP usually handles higher temperatures and a broader range of chemicals than PVC. PVC can be a lower-cost choice for cold water duties.
When should I choose PVDF instead of PP?
Choose PVDF for hot liquids, strong oxidisers such as chlorine or hypochlorite at higher strengths, and many solvents.
Do you make custom PP nozzles?
Yes. Send a sample, drawing or your requirements and we will advise on size, pattern and connection.
